Please fill in the following information:

Issue description: In RH11-9.0 in section ch13s07 it says the following: "The getent hosts hostname command tests hostname resolution with the /etc/hosts file. If an entry is not found in the /etc/hosts file, then the stub resolver uses a DNS name server to look up the hostname. The /etc/resolv.conf file controls how this query is performed:" The last sentence is wrong, Wrong, WRONG. The correct statement is "The /etc/nsswitch.conf file controls how this query is performed". The "getent hosts hostname" will only work if nsswitch.conf is correctly configured with at least "hosts: files" enabled. If not, no amount of editing /etc/resolv.conf can make it work. If it should continue resolution with DNS second, the configuration would be "hosts: files dns".
